Abstract
|
|
|
|
This study was conducted to develop the domestic production of a controlled atmosphere (CA) storage system, including nitrogen generator and carbon dioxide eliminator using selective gas separation membrane and operating program. Generally, the gas composition inside general cold stores constantly changes due to the metabolic activity of the respiring vegetables and fruits and leakage of gases through doors and walls. However, the CA container developed by our research team is able to control of the level of oxygen and carbon dioxide inside the reefer, making it simple and effective in operation. The efficiency of the nitrogen generator to replace oxygen with nitrogen inside the CA container was approximately 1.33% per hour. The change in oxygen concentration inside the CA container during the operation refrigerator almost did not show any difference for 8 days. Therefore, CA storage container should be a promising approach to maintaining the high quality of agricultural products during storage.
